Description

【0001】
【発明の属する技術分野】
本発明は、建築外装用にその寸法が標準化されて用いられる断熱パネル材およびその製作方法に関し、特に鉄骨造建築物の外断熱工法に適した外装下地パネルおよびその製作方法に関する。
【0002】
【従来の技術】
省エネルギーや居住環境の質的向上の観点から、住居の断熱構造に対して関心が高まっている。木造住宅の場合、その外壁は内装材、外装下地材、外装材からなり、断熱法として内装材と外装下地材とで構成される壁体内に断熱材を施工する充填断熱が最も一般的だが、近年になって、外装下地材の屋外面に断熱材を配した外張り断熱が増加してきている。
【0003】
一般的に断熱材の施工は手間がかかるため、断熱材を組み込んだパネルを用いるパネル工法が開発されている。パネル工法は、外周枠と縦胴縁(間柱)からなる枠組、面板、枠組の内外に配置される断熱材を基本構成としたパネルを柱、梁に囲まれた範囲に嵌めこんで取りつけることによって、耐力壁を構成し、パネルの枠組が躯体の間柱を兼用する。
【0004】
鉄骨住宅においては、近年、柱、梁、ブレースの鉄骨プレカット部材と、接合金物をキット化した鉄骨住宅用フレーム(以下、フレームキット(JFEスチール登録商標))が販売されている。
【0005】
フレームキットを用いると、現場での鉄骨の切断や溶接加工が不要となり、ボルト、ナットで木造感覚で組立ができ、これまで、鉄骨造になじみのない木造工務店でも扱えることを特徴とする。その他の二次部材や内外装は、木造住宅の納まりを踏襲して組み立ている場合が多い。
【0006】
鉄骨住宅の場合、構造体の熱伝導率が高く、ヒートブリッジによる熱損失の増加や、表面温度低下による結露が生じるため、柱の内外面が断熱されない充填工法は不適で、外張り断熱が好ましく、外張り形式のパネルが用いられる。
フレームキットの場合、柱は角形鋼管あるいは軽量形鋼、土台および梁はH形鋼、ブレースはターンバックルブレースからなり、柱の外面が梁フランジの外面と同じ位置あるいは梁フランジよりも屋外側となるように計画されている。柱の断面寸法が小さい場合には、梁の屋外側に寄せて設置する、あるいは柱の外面にスペーサーを配置する等の方法を用いる。ブレースは壁体内の梁芯を中心に対象形で配置される。
【0007】
特許文献1、2は外張り形式のパネルに関し、特許文献1には枠材内部に断熱材が配置され、屋外側に気密層、面板と積層して構成された、軸組の屋外側に取り付けられるパネルが記載されている。
【0008】
特許文献2には、フレームキット用に開発された外張り形式のパネルであってLVLによる外周枠に枠の内法寸法よりもやや大きな外形寸法の一体ものの断熱材が嵌めこまれ、その屋外側表面に防水シートが接着され、鉄骨梁に設けてあるブラケットに固定する取り付け金具を一体化して備えているものが記載されている。開口部では隣接して設置するパネルの開口枠の高さ位置にパネル裏面から横桟材を付加して補強を行う。
【0009】
【特許文献1】
特開2000−170277号公報
【0010】
【特許文献2】
特開2000−104368号公報
【0011】
【発明が解決しようとする課題】
しかしながら、特許文献1、2記載の外張り形式のパネルを、フレームキットに適用する場合、以下に述べる問題点を解決しなければならない。
【0012】
特許文献1記載の発明に係るパネルは、枠材内部に断熱材が配置され、屋外側に気密層、面板と積層して構成され、軸組の屋外側にとりつけられるため、フレームキットのブレースと干渉しない。
【0013】
しかし、枠構成が縦枠中心のため、それぞれの縦枠の上下端部を連結する上下枠部分を梁部に強固に接合する必要があるが、開断面となるフレームキットの梁への取り付けは困難で、風圧力に対して耐力を保持できないことが懸念される。また、パネル構成上、外装材裏面に侵入した水分が面板に染み込み耐久性が懸念される。
【0014】
更に、パネル相互の接合構造が、枠材とパネル板の端部を幅方向にずらし、一方に張出部、他方に縦枠露出部を設け、相互に勘合させる形式であり、片側から順に施工しなければならない。
【0015】
一般的に一つの建物では細部の異なる複数のパネルを使用しなければならないため、このような接合構造ではパネル割り付け、製造管理、施工管理の手間が大きくなることが懸念される。
また、開断面である梁部に対する断熱材および通気用縦胴縁の取り付け方法についての記載はない。
【0016】
特許文献2記載の発明に係るパネルは、フレームキット用であり、ブレースとの干渉、梁部の取り付け、上下パネルの接合、および開口部まで考慮されている。
【0017】
しかし、パネル枠内に補強縦枠や横桟材が配置されていないため、ALCのように厚い外装材を用いる場合を除いて、耐風設計上、幅は500mm内外に制約される。その結果、部品点数が増えるため施工効率が阻害されることが懸念される。
【0018】
断熱材が一体もので大型であり、枠の内法寸法よりも大きいため、枠に嵌めこむ手間は非常に大きい。さらに、記載されている取り付け方法では開口部下部への取り付けは不可能なため、新しいパネルを別途開発しない限り、現場合わせの施工を余儀なくされる。
【0019】
パネルの高さ寸法を階高としているため、標準パネルとして現場に搬入した場合、オーバーハング、ベランダ、など、上部に床梁が突出する部分では、パネルの構造強度を担う枠上部を切除しなければならず、パネルの強度が著しく損なわれ、強風時には外装材が崩落することが懸念される。
特許文献1、2には、入隅、オーバハング、セットバック、ベランダ、バルコニーなど標準化された寸法のパネルの適用が困難な個所へ、これら特許文献に記載の発明に係るパネルをどのように適用施工するか一切記載されていない。
【0020】
本発明は、上述した問題点、すなわち1.パネルの耐風強度、2.パネル相互の接合性、3.標準寸法のパネルの入隅部等への対応性、4.パネルの製造性、5.施工性をそれぞれを向上させた外張り断熱パネルおよび施工方法を提供することを課題とする。
【0021】
【課題を解決するための手段】
本発明の課題は以下の手段により解決される。

【0022】
【発明の実施の形態】
本発明に係る外装下地パネルは、住宅外壁で入隅、オーバハング、セットバック、ベランダ、バルコニーなどを除いた部分(以下一般部)における、上梁、下梁、柱で構成され、これらの屋外側の面が同一平面上にあり、柱の中心間距離が、910mm〜1000mmの間口を対象とする。
【0023】
住宅の一般部での同じ寸法の複数の間口に適合するように、本発明に係る外装下地パネルは標準化された寸法で用いられる。尚、下梁には土台を含むものとする。以下、本発明について図面を用いて詳細に説明する。
【0024】
図1は請求項1記載の発明に係る外装下地パネルの屋外側の斜視図を示し、図において1は、外装下地パネル、2a,2bは縦胴縁、3aは上端の横胴縁、3bは下端の横胴縁、3cは中間の横胴縁、4は面板、5は断熱材、H1は枠組の高さ、W1は枠組の幅、H2は面板の高さ、W2は面板の幅、hは横胴縁の高さを示す。
【0025】
外装下地パネル1は、一対の縦胴縁2a,2bとその間に架設される複数の横胴縁3a,3b、3cで構成された枠組に、面板4を前記枠組の屋内側に取付けて構成され、縦胴縁と横胴縁に囲まれた領域の全てには断熱材5が充填される。
【0026】
枠材の断面寸法や一対の縦胴縁2a,2bの間に架設する横胴縁3cの間隔は、所望の特性が得られるように構造設計により設定する。例えば、横胴縁3cは、枠組の高さ方向に均等に割り付けたり、製作管理を容易にするため、枠材の高さによらず、予め決めた基準寸法で取付け、余剰部を残しても良い。
【0027】
枠組の高さH1は、外装下地パネル1が適用される間口を構成する上下の梁間の内法高さ以下、枠組の幅W1は前記間口の柱の中心間距離以下、内法間隔以上とする。
【0028】
一対の縦枠と複数の横胴縁を設けた強固な枠組構造とすることにより、柱への固定箇所を通常より少なくすることができ、また、間口において耐風設計上、従来必要とされていた間柱の省略が可能となる。
【0029】
枠材の素材は断熱性に優れた素材であればよく特に規定しないが、現場加工が容易な木材、構造用集成材、LVLなど木質系材料が好ましい。
【0030】
面板4は、柱の屋外側の面に当接するように枠組の屋内側の面に取付け、且つ、枠組の上下に突出する部分(延長部)が生ずるように取付ける。面板4の高さH2は、枠組の下方側にその長さを「枠組の下端から下梁の下端までの長さ以下」とする延長部を突出させ、枠組の上方側にはその長さを「上梁のせいから前記下方側の延長部長さを減じた長さ以下」する延長部を突出させる高さとする。
【0031】
延長部の長さは、最も小さい梁のせいを基準に計画すると、各階共通の標準パネルが得られる。フレームキットの場合、土台のせいが最も小さいため、下方への延長寸法は、土台せいを基準に計画すると良い。
【0032】
上下の延長部の長さを等しくすることも可能で、その場合、現場において上下方向の管理が不要となる。面板4の幅W2は枠組の幅以上、間口の柱の中心間距離以下とする。
【0033】
尚、本発明では、外装パネルを間口に取付ける際、前記枠組の下面が下梁上面の位置に一致するように取付ける。
【0034】
図10〜12は外装パネル1と間口の上梁、下梁との取り合いを説明する図で、これらの図において14は柱、15は下梁(土台)、16は基礎、17は上梁を示す。
【0035】
図10は外装下地パネル1と基礎16の取り合いを示し、面板4の下方への延長部を「枠組の下端から下梁の下端までの長さ以下」の長さとするため、クリアランスが生じ、前記下方延長部は基礎16に干渉せず、断熱材を取付け、下梁(土台)15側面の外断熱が可能となる。
【0036】
図11は上下階に取り付けられた外装下地パネル1a,1bと梁20の取り合いを示し、外装下地パネル1bの上方への延長部を「上梁のせいから前記下方側の延長部長さを減じた長さ以下」の長さとし、外装下地パネル1aの下方への延長部の長さを「枠組の下端から下梁の下端までの長さ以下」とするため、これら延長部は干渉せず、断熱材5を取付け、梁(20)側面の外断熱が可能となる。
【0037】
図12は最上階における外装下地パネル1と梁17の取り合いを示し、上方への延長部に、断熱材5を取付け、梁17の外断熱を行う。
【0038】
面板の素材は、当接する上下の梁や柱と熱橋を形成しないように断熱性に優れ、且つ一定の強度、剛性と現場加工性を有するものであれば良く、特に規定しない。例えば、合板、パーティクルボード、MDF(中質繊維板)、シージングボード(軟質繊維板)、木毛セメント板、木片セメント板などに代表される木質系材料、アクリル板、ポリカーボネート板、ポリエチレン板、ポリプロピレン板、ABS樹脂板などに代表される樹脂系材料、石膏ボード、火山性ガラス質複層板、珪酸カルシウム板などに代表される無機系材料が使用できる。
【0039】
断熱材5は、縦胴縁、横胴縁及び面板に囲まれた箱状の領域に配置する。断熱材の素材は特に限定しないが、グラスウール、ロックウールなどに代表される無機繊維系断熱材、セルロースファイバーなどに代表される有機繊維系断熱材、発泡ポリスチレン、発泡ポリエチレン、フェノールフォーム、ウレタンフォームなどに代表されるプラスチック系断熱材などが使用できる。
【0040】
繊維系断熱材の場合は、面板の屋外側あるいは屋内側にポリエチレンシートなど防湿層を配置するか、面板に非透湿性の材料を選択し、室内からの水蒸気を遮断することが好ましい。プラスチック系断熱材は大きめの寸法のものを嵌めこむ、接着剤、両面テープ、固定金具などにより固定する。
【0041】
図5は、ビーズ状発泡ポリスチレンなどのビーズ状発泡体で断熱材5をパネルと一体に形成する方法を説明する図で、横胴縁と縦胴縁に囲まれた領域にビーズ状発泡体を充填し、開口部分を型枠材11で覆った後、加熱する。
【0042】
本法によれば、断熱材が、容易な施工で、枠材に対し隙間無く強固に固着され、運搬時、施工時の断熱材脱落防止、断熱性向上、耐久性向上がはかられる。
【0043】
以上が本発明に係る外装下地パネルの基本構成であり、更に、防水性や気密性を向上させることが可能である。
【0044】
図2は、防水性、気密性を向上させた外装下地パネル1の屋外側平面図を示し、屋外面側に樹脂シート6がタッカー釘など固定具7または接着材による接着部8により装着されている。
【0045】
上下左右に隣接する外装下地パネルの樹脂シートと重ね合わせられるように、樹脂シート6の高さは面板の下端部から面板の上端部以上とし、幅は面板の幅より広くする。
【0046】
また、重ね合わせが容易なように枠組への取付けは枠組の外周側から所定の長さだけ内側に入った位置で横胴縁に固定具7で取付ける。
【0047】
樹脂シート6の素材は、透湿性、防水性および気密性を有するものが好ましいが、特に規定しない。
【0048】
図14は外装下地パネル1c,1dの隣接部における樹脂シートの取り合いを説明する水平断面図で、外装下地パネル1c,1dの面板4が柱14に当接している。
【0049】
樹脂シート6cは外装下地パネル1cの面板4より、幅が広く、縦胴縁2aより内側となる位置で横胴縁に固着されているので(a)、隣接部で樹脂シート6c,6dを重ね合わせることが可能で(b)(c)、その後、必要に応じて、通気胴縁9cを隣接部に取付ける(d)。
【0050】
図3は、その屋外面に通気用縦胴縁9a,9b,9cを取付けた外装下地パネル1の斜視外観図(a)と水平断面図(b)を示し、通気用縦胴縁は枠組の屋外側正面の中央部または中央部および両端部に鉛直方向に予め取付けられている。
【0051】
通気用縦胴縁を両端部に取付ける場合は、樹脂シートの幅を枠組の幅に一致させる。
【0052】
通気用縦胴縁9a,9b,9cを外装下地パネル1に取付ける場合は、枠組の上端の横胴縁3a,下端の横胴縁3bは、中間の横胴縁3cを2段に重ねたり、中間の横胴縁3cの高さhより高い部材を用いて、その高さhを高くする。
【0053】
通気用縦胴縁9a,9b,9cの長さはその上部の端面が前記上端の横胴縁3aの高さhの中間部に位置し、その下部の端面が前記下端の横胴縁3bの高さhの中間部に位置する長さとする。
【0054】
枠組の上下端面と通気用縦胴縁の上下端面に段差を設けることにより、上下に隣接する外装下地パネル間の、梁部通気用縦胴縁の取付け作業が容易となる。
【0055】
縦胴縁2a,2bに沿って、通気用縦胴縁9b,9cを予め取付けておく場合は、縦胴縁2a,2bの外周側側面と通気用縦胴縁9b,9cの外周側側面が一致するようにし、通気用縦胴縁9b,9cの隅角部全長にシーリング剤の充填用に面取り状の切欠部を設ける(A−A´断面)。
【0056】
図15は柱に左右に隣接して外装下地パネルを取付ける方法を説明する図で水平断面図を示す。外装下地パネル1c、1dを柱14に取付け(a)(b)、左右に隣接する外装下地パネルの通気用縦胴縁9a,9bの切欠部にシーリング剤18を充填する。
【0057】
図13は樹脂シートと通気用縦胴縁を備えた外装下地パネルを、梁部の上下に取付ける方法の一例を説明する図で鉛直断面図を示す。上となる外装下地パネル1aの樹脂シート6aは、面板4aの下端部までの長さで、下となる外装下地パネル1bの樹脂シート6bは面板4bの上端部より長く(a)、上となる外装下地パネル1aの下端部横胴縁中間部に達する長さで、断熱材5を面板4a,4bに掛け渡して梁15の側面を覆った後(b),樹脂シート6bをタッカー釘等の固定具で、上となる外装下地パネル1aの下端部横胴縁に固定し、樹脂シート6aを上から重ね合わせ、重ね合わせ部に気密テープ19を貼る(c)(d)(e)。
【0058】
樹脂シートの処理が終了した後、梁部通気用縦胴縁9dを取付け、上下外装下地パネルの通気用縦胴縁を連続させる。外装下地パネルの、枠組の上下端面と通気用縦胴縁の上下端面の段差により、梁部通気用縦胴縁の取付け作業は容易である(f)。
【0059】
図4は、外装下地パネル1の屋内面側の斜視外観図を示し、間口の下梁上面に外装下地パネル1が仮設できるように、突起部10a,10bが、面板4に下端部横胴縁の下面と前記突起部10a,10bの下面が一致するように設けている。突起部の設置位置は、これに限定するものではなく、上下梁のいずれかに仮設可能なように、枠組の下端部横胴縁、上端部横胴縁の少なくとも一つに相当する位置で、面板の屋内側に設ければよい。
【0060】
次に本発明に係る外装下地パネルから、一般部以外の入隅、オーバハング、セットバック、ベランダ、バルコニーなどの部分に適用するパネルを製作する方法について説明する。
図6は開口部パネルの製作方法を説明する図で、外装下地パネルを建具のラフ開口位置でその寸法に応じて切断し(a)、切断面の全幅に渡って新たに横胴縁12a,12bを取り付ける(b)。
【0061】
図7は入隅部パネルの製作方法を説明する図で、外装下地パネルを入隅部で相互に干渉しない寸法で切断し(a)、必要に応じて枠組の切断面の全長にわたって縦胴縁を取付ける(b)。
【0062】
図8はオーバハング部パネルの製作方法を説明する図で、外装下地パネルの上端部横胴縁より突出した面板部分(上方延長部)を切断し(a),必要に応じて切断した面板を上端部の横胴縁上面に屋外側に突出するように取りつける(b)。
【0063】
図9はセットバック部パネルの製作方法を説明する図で、外装下地パネルの下端部横胴縁より突出した面板部分(下方延長部)を切断し(a)、必要に応じて切断した面板を下端部の横胴縁下面に屋外側に突出するように取付ける(b)。
【0064】
尚、本発明に係る外装下地パネルは、外装材を特に限定せず、ALC,窯業系サイディング、押出し成形セメント板、金属サイディング等を用いることができる。
【0065】
【発明の効果】
本発明によれば、相互に干渉せずに、隣接して配置することが可能で、強度、気密性、防水性、施工性に優れた外装下地パネルが得られるため、鉄骨造住宅に外断熱工法が容易に適用でき、省エネルギー、耐久性向上に極めて有用である。
【0066】
また、本発明に係る外装下地パネルでは、その幅を間柱を必要としない寸法とするため、住宅構造を単純化でき、建設コストを低減できる。

In general, construction of a heat insulating material takes time, so a panel method using a panel incorporating a heat insulating material has been developed. The panel construction method is to install a frame composed of an outer peripheral frame and vertical body edge (intermediate column), a face plate, and a panel based on the heat insulating material arranged inside and outside the frame by fitting it in the area surrounded by the pillar and beam. It constitutes a bearing wall, and the frame of the panel also serves as a pillar of the frame.
[0004]
In steel frame houses, in recent years, steel frame frames (hereinafter referred to as frame kit (JFE Steel registered trademark)) in which steel frame pre-cut members such as columns, beams, and braces and joint hardware are made into kits are sold.
[0005]
The use of the frame kit eliminates the need for cutting and welding of steel frames on site, making it possible to assemble with bolts and nuts like a wooden structure, and it can be handled by wooden construction shops that are not familiar with steel structures. Other secondary members and interior / exterior are often assembled following the housing of wooden houses.
[0006]
In the case of steel-framed houses, the thermal conductivity of the structure is high, and heat loss due to heat bridges and condensation due to a decrease in surface temperature occur.Therefore, the filling method in which the inner and outer surfaces of the columns are not insulated is unsuitable, and the outer insulation is preferable. External panel is used.
In the case of the frame kit, the pillar is a square steel pipe or light-weight steel, the base and the beam are H-shaped steel, the brace is a turnbuckle brace, and the outer surface of the column is at the same position as the outer surface of the beam flange or outside the beam flange. Is planned. When the cross-sectional dimension of the column is small, a method such as placing the column close to the outdoor side of the beam or arranging a spacer on the outer surface of the column is used. The brace is arranged in a target shape around the beam core in the wall.
[0007]
Patent Documents 1 and 2 relate to an outer panel, and in Patent Document 1, a heat insulating material is arranged inside a frame member, and is attached to an outdoor side of a shaft assembly which is configured by laminating an airtight layer and a face plate on the outdoor side. Panel is described.
[0008]
Patent Document 2 describes an external panel developed for a frame kit, in which an insulating material having an outer dimension slightly larger than the inner dimensions of the frame is fitted in an outer peripheral frame made of LVL, and its outdoor side There is a description in which a waterproof sheet is bonded to the surface, and an attachment fitting that is fixed to a bracket provided on a steel beam is integrated. At the opening, a crosspiece is added from the back of the panel to the height position of the opening frame of the panel to be installed adjacently to reinforce.

[Problems to be solved by the invention]
However, when applying the external panel described in Patent Documents 1 and 2 to a frame kit, the following problems must be solved.
[0012]
The panel according to the invention described in Patent Document 1 has a heat insulating material arranged inside the frame material, and is configured by laminating an airtight layer and a face plate on the outdoor side, and is attached to the outdoor side of the frame assembly. Does not interfere.
[0013]
However, because the frame configuration is centered on the vertical frame, it is necessary to firmly join the upper and lower frame parts connecting the upper and lower ends of each vertical frame to the beam part. It is difficult to maintain the proof strength against wind pressure. Further, due to the panel configuration, moisture that has penetrated into the back surface of the exterior material soaks into the face plate, and there is a concern about durability.
[0014]
Furthermore, the joint structure between the panels is a form in which the ends of the frame material and the panel plate are shifted in the width direction, an overhanging part is provided on one side, and a vertical frame exposed part is provided on the other side. Must.
[0015]
In general, a single building must use a plurality of panels with different details, and there is a concern that such a joint structure may increase the time required for panel allocation, manufacturing management, and construction management.
Moreover, there is no description about the heat insulating material with respect to the beam part which is an open cross section, and the attachment method of the vertical trunk edge for ventilation | gas_flowing.
[0016]
The panel according to the invention described in Patent Document 2 is for a frame kit, and is considered to include interference with braces, attachment of a beam portion, joining of upper and lower panels, and an opening portion.
[0017]
However, since the reinforcing vertical frame and the crosspiece are not arranged in the panel frame, the width is limited to 500 mm inside and outside in the wind resistant design, except when a thick exterior material such as ALC is used. As a result, there is a concern that construction efficiency is hindered because the number of parts increases.
[0018]
Since the heat insulating material is integrated and large, and is larger than the internal dimensions of the frame, it takes a lot of trouble to fit it into the frame. Furthermore, since the attachment method described cannot be attached to the lower portion of the opening, unless a new panel is separately developed, construction on the site is unavoidable.
[0019]
Since the height of the panel is the floor height, when the standard panel is brought into the field, the upper part of the frame that bears the structural strength of the panel must be cut off at the part where the floor beam protrudes at the top, such as overhang, veranda, etc. Therefore, the strength of the panel is remarkably impaired, and there is a concern that the exterior material collapses in a strong wind.
In Patent Documents 1 and 2, how to apply the panel according to the invention described in these Patent Documents to the places where it is difficult to apply the standard size panels such as corners, overhangs, setbacks, verandas, and balconies. It is not described at all.
[0020]
The present invention has the above-mentioned problems. 1. Wind resistance of the panel 2. Bondability between panels; 3. Compatibility with corners of standard size panels, etc. 4. Manufacturability of panels It is an object of the present invention to provide an external heat insulating panel and a construction method that improve the workability.

[0023]
The exterior base panel according to the present invention is used in a standardized size so as to fit a plurality of frontage of the same size in the general part of the house. The lower beam includes the foundation. Hereinafter, the present invention will be described in detail with reference to the drawings.
[0024]
FIG. 1 is a perspective view of an exterior base panel according to the first aspect of the present invention on the outdoor side. In FIG. 1, 1 is an exterior base panel, 2a and 2b are vertical trunk edges, 3a is a top horizontal trunk edge, and 3b is The lower horizontal trunk edge, 3c is the intermediate horizontal trunk edge, 4 is the face plate, 5 is the heat insulating material, H1 is the height of the frame, W1 is the width of the frame, H2 is the height of the face plate, W2 is the width of the face plate, h Indicates the height of the lateral torso edge.
[0025]
The exterior base panel 1 is configured by attaching a face plate 4 to the indoor side of the frame on a frame composed of a pair of vertical drum edges 2a, 2b and a plurality of horizontal drum edges 3a, 3b, 3c. The entire region surrounded by the vertical and horizontal waist edges is filled with a heat insulating material 5.
[0026]
The cross-sectional dimension of the frame member and the interval between the horizontal trunk edges 3c installed between the pair of vertical trunk edges 2a and 2b are set by structural design so that desired characteristics can be obtained. For example, the horizontal torso edge 3c can be evenly allocated in the height direction of the frame or can be easily managed, so that it can be attached with a predetermined reference dimension regardless of the height of the frame, and the surplus portion can be left. good.
[0027]
The height H1 of the frame is equal to or less than the inner height between the upper and lower beams constituting the front opening to which the exterior base panel 1 is applied, and the width W1 of the frame is equal to or smaller than the distance between the centers of the front pillars and equal to or larger than the inner distance. .
[0028]
By adopting a strong frame structure with a pair of vertical frames and a plurality of horizontal torso edges, the number of places fixed to the pillar can be reduced than usual, and it was conventionally required for wind resistance design at the frontage. It is possible to omit the studs.
[0029]
The material of the frame material is not particularly limited as long as it is a material excellent in heat insulating properties, but wood-based materials such as wood, structural laminated material, and LVL, which are easy to process in the field, are preferable.
[0030]
The face plate 4 is attached to the indoor side surface of the frame so as to come into contact with the outdoor side surface of the column, and is attached so that portions (extensions) projecting up and down of the frame are generated. The height H2 of the face plate 4 is such that an extension portion having a length "below the length from the lower end of the frame to the lower end of the lower beam" protrudes on the lower side of the frame, and the length is set on the upper side of the frame. The height is defined as a height at which the extension portion that protrudes below the length obtained by subtracting the length of the extension portion on the lower side from the upper beam protrudes.
[0031]
If the length of the extension is planned based on the smallest beam, a standard panel common to each floor can be obtained. In the case of a frame kit, since the foundation is the smallest, the downward extension should be planned based on the foundation.
[0032]
It is also possible to make the lengths of the upper and lower extensions equal, and in that case, vertical management is not required at the site. The width W2 of the face plate 4 is not less than the width of the frame and not more than the distance between the centers of the front pillars.

[0036]
FIG. 11 shows the connection between the exterior base panel 1a, 1b and the beam 20 attached to the upper and lower floors. The upper extension of the exterior base panel 1b is expressed as “the extension length on the lower side is reduced because of the upper beam. Since the length of the extension portion below the exterior base panel 1a is set to be “the length from the lower end of the frame to the lower end of the lower beam”, these extension portions do not interfere with each other and are insulated. The material 5 is attached and the heat insulation of the side surface of the beam (20) becomes possible.
[0037]
FIG. 12 shows the connection between the exterior base panel 1 and the beam 17 on the uppermost floor, and the heat insulating material 5 is attached to the upward extension portion to perform the heat insulation of the beam 17.
